Patent CA-2105647-C (CA)
Inventor: SCHINDEL DAVID W
IPC: H04R17/00
Filed: 1993-09-07
Granted: 1999-12-14
Abstract: An acoustic transducer which is operable in air up to at least 2MHz is described. A conducting substrate, usually a silicon wafer is etched to provide a selected pattern of micro pits up to about 30µm or more deep. A dielectric film, such as a polyimide film is placed over the etched surface so as to trap air in each individual pit. A conducting upper layer is then superimposed over the dielectric film. When a potential is applied between the substrate and the upper layer the upper layer is driven into motion and enhanced by the vibrations of the air pockets. Alternatively a smooth substrate may be employed in conjunction with an etched dielectric film to achieve the same result. These transducers are useful for non-destructive testing of large structures or for medical diagnostic and therapeutic purposes, without the need for a liquid or gel coupling agent.

Granted: 1997-10-07
Abstract: A parallel data transfer circuit wherein processing at a data transfer source circuit is simplified to reduce the time required for transfer and a data storage area of a data transfer destination circuit can be used effectively is disclosed.  A plurality of data register sets for temporarily latching parallel data and a plurality of corresponding flag register sets are provided between a data transfer source circuit and a data transfer destination circuit.       A register designation signal is outputted from the data transfer source circuit to designate a data register into which data should be written.  Only when data should be written into the data register, a flag is placed into a corresponding flag register.  Since the data transfer destination circuit fetches data only of those data registers corresponding to those flag registers in which a flag is held, parallel data can be received without forming a discontinuous empty portion in data storage area of the data transfer destination circuit.

Abstract: There is provided a device (10) for orientating a load to be suspended and moved by a crane. The device (10) comprises a flywheel (11) mounted for rotation in a housing (14). A turntable (17) is pivotally connected to the housing (14) and is drivable relative to the housing using a driven worm gear (23) meshing with an annular set of teeth (22) on the turntable (17). The turntable has an axle (18) to which loads can be attached. When the flywheel (11) is spinning at high speed it resists movement out of its plane of rotation so as to stabilise the cable in winds, etc. The flywheel (11) also allows the worm gear to react against it so as to turn the load relative to the flywheel (11). Maneuvering of the load is therefore made easier.
